During my internship, I was responsible for the end-to-end development of a comprehensive Power BI dashboard. This included not only the visualization of key metrics but also the entire data preparation process. I designed and implemented an Operational Data Store (ODS) and a Data Warehouse from scratch, utilizing ETL processes with SQL Server Integration Services (SSIS) to ensure data was accurately filtered, transformed, and loaded. This experience allowed me to gain hands-on expertise in data management, reporting, and the use of industry-standard tools to deliver actionable insights.
